Definitions

  • the invention relates to an industrial truck, in particular a forklift, with a Load handler and one opposite to the load handler arranged counterweight, a drive arrangement operable with hydrogen and a storage for hydrogen.
  • Industrial trucks of the type mentioned have a load suspension device Handling loads that are usually liftable on a mast Includes fork. If, like forklifts, the load fork and thus the center of gravity of an absorbed load outside the wheel base of the Truck is to compensate for the weight of the load Counterweight required.
  • the counterweight is on the Load handling device arranged opposite end of the truck, at Forklift trucks, the rear of the vehicle is formed by the counterweight.
  • the counterweight is made of cast steel and forms part of the load-bearing structure of the industrial truck.
  • the invention has for its object to provide an industrial truck with an advantageous to provide arranged storage.
  • the memory at least is partially arranged in the area of the counterweight.
  • the memory is in the Industrial truck also opposite to the load suspension device arranged, whereby the weight of the memory also acts as a counterforce to the Weight of a raised load acts.
  • the accumulator is preferably arranged completely in the area of the counterweight. This allows any part of the memory to compensate for the weight of a raised load can be exploited.
  • the amount of material required to produce the counterweight can be reduced be used to compensate for those acting on the load suspension device Forces required counterforce together from the mass of the counterweight and the mass of the memory is generated.
  • the mass of the storage is at Determination of the mass of the counterweight taken into account from the outset.
  • Metal hydride storage enables that Storage of hydrogen at ambient temperature and are for example off automotive hydrogen test vehicles are known, but are due there hardly used because of their high weight.
  • Typical data for metal hydride storage are for example, a weight of 300 kg with 2 kg of hydrogen storage capacity and 160 Liters of installation space.
  • Optimal use of space within the industrial truck can be achieved if the memory is constructed in several parts. There can be several small ones Memory can be used instead of a large memory. The memory can be in Normally over the entire lifespan of the truck in the Truck remain, so no special requirements with regard Accessibility and interchangeability of the storage exist.
  • At least part of the memory arranged above the counterweight is arranged above the counterweight.
  • At least part of the memory is in the region of the Top of the counterweight, for example in a recess of the Counterweight is arranged.
  • the high thermal conductivity and the large heat capacity of the counterweight can be exploited if the memory with the counterweight is connected that a heat transfer between the counterweight and the Memory is enabled.
  • enter Metal hydride stores heat. This heat can be transferred to the counterweight that heats up.
  • a ventilation device can be used to remove heat from the store be provided.
  • the ventilation device allows air cooling of the Storage, especially during the filling with hydrogen.
  • the drive arrangement preferably has at least one fuel cell.
  • Fuel cell is removed from the memory in a known manner Hydrogen and electrical energy from ambient oxygen, with which the Aggregates of the industrial truck, in particular a travel drive and a lifting drive be supplied with electrical energy.
  • the drive arrangement has at least one internal combustion engine.
  • the one taken from memory Hydrogen can be burned in an internal combustion engine, which is then emitted a suitable gearbox for the drive and a hydraulic pump for the Linear actuator drives.
  • Figure 1 shows the side view of a designed as a forklift industrial truck according to the invention.
  • the forklift has two front wheels 1 and two rear wheels 2 on a lane.
  • a vehicle frame 3 is arranged, on which directly or indirectly various units of the forklift, a driver's cab 4, a mast 5 and a counterweight 6 are attached.
  • a load suspension device 7 designed as a load fork can be moved up and down attached.
  • the load fork is located and thus also the center of gravity of a load that may have been absorbed outside the wheel base.
  • the gravity of the load is therefore generated one acting clockwise around the contact line 8 of the front wheels 1 Torque. This torque is determined by the weight of the counterweight 6 counteracted that at the rear end of the forklift, opposite to that Load suspension device is arranged.
  • the forklift has a drive device which can be operated with hydrogen (H 2 ) and which is arranged in the region of the vehicle frame 3.
  • a store 9, 10 for hydrogen designed as a metal hydride store is arranged in the area of the counterweight 6.
  • the memory 9, 10 is designed in two parts in the embodiment shown. A first part 9 of the memory extends in the transverse direction of the forklift and is arranged at a slight distance in front of the counterweight 6. A second part 10 of the store is located in the upper part of the counterweight 6 in a recess created during the manufacture of the counterweight 6.
  • the weight of the memory 9, 10 be exploited to the torque generated by a raised load counteract.
  • it can Mass can be reduced compared to a forklift without hydrogen storage.
  • the Arrangement of the memory 9, 10 inside the vehicle frame 3 and within the outer contours of the counterweight 6 protects the memory 9, 10 from outer Influences and damage, e.g. as a result of an accident.
  • FIG. 2 shows the industrial truck according to the invention in plan view. It can be seen in particular the arrangement of the two parts of the memory 9, 10 for hydrogen.
  • the when refueling the store 9, 10 designed as a metal hydride store free Heat can be at least partially absorbed by the counterweight 6 be, which heats up only moderately due to its large mass.
  • this can be done via a Forced ventilation can be achieved, in which preferably the entire surface 9, 10 flow around the memory.
  • the guidance of the cooling air can be done in the Counterweight 6 channels incorporated.
  • the direction of the cooling air flow is in the figure 2 with arrows 11, 12 illustrates. If in the area of the counterweight 6 other heat-generating components, e.g. an electrical control unit is arranged are, the heat capacity of the counterweight 6 and one if necessary Existing cooling air flow is also used to cool this additional component become.
